关于 天文单位 (au)
Originally based on Earth's mean distance from the Sun, the astronomical unit (AU) was fixed in 2012 at exactly 149,597,870,700 meters. Planetary scientists use AUs to express distances within the solar system: Mars orbits at about 1.52 AU, Jupiter at 5.2 AU, and the outer edge of the Kuiper Belt at roughly 50 AU.
关于 光年 (ly)
The distance light travels in one Julian year -- approximately 9.461 trillion kilometers -- the light-year is the standard unit for expressing interstellar distances. Proxima Centauri, the nearest star beyond the Sun, lies about 4.24 light-years away. Despite its name, the light-year measures distance, not time.
